' To all whom t may concern:

Be itkno'wrthat I, I-IUGH C. Lonn, a citil zenofthe United States,residing at Erie,

in the county of Erie and` State of Pennsyl- Iby its distortion orstretch accommodates the Lmovement ofthe joint. Withl such devices e invorder to provide -for it is often desirab the wall or rubber to use acomparatively small pin and where this is donein order to sustain theload to which the joint is subjected it is desirable to support the pinat a number of places so that the tendency to i section, of a knucklejoint of an automobile."y Fig. 2 an enlarged .section of the joint- ',35as clearly s own in-Fig.2. jThus the lspace bend the in is largelyremoved. Thev in` vention urther contemplates a vertical jolnt. Whereinserts of -rubber are used 1n a vertical joint it is de'sirableto spacethe units of the joint so that when the joint is subjected to the loadthe lunits will be propj.

erly spaced.Y The invention also contemplates aconstructionwhi'chfacilitates thev assembling of a joint having rubberinserts"l with a central loatin'g'pin. The'. invention furthercontemplatessthe connecting up of joints of this general type.

The invention is illustrated in the accom "j .panying drawings asfollows Fig. 1 shows a front elevation, partly in element.-

Fig. 3 an end elevation of a shackle or joint, the joint being partly insection.

.y of projections 4 through which extend the .75 and the knuckle' has aseries of projections 6 gthroughwhich' extend the screw-threadedopenings 7 -,The

, ,so that.'- they may be placed alternately" ringing the openin Fig. 4a section on the line 4-4 in Fig. l3. Fig. 5 a section on the-line 5-5in Fig. 1. 1 marks the axle,'2 vthe knuckle,-and ,3 the hub of a wheel.The axle lias a plurality screw-threaded openin projections 4 and 6 -arearr into register.j.A pivot- 1n 8 ex'- tends t rough the pe'mng.-v -Rubr members-9 are bonded b surface bonding, rac-v complished -prefera ly.during vulcanlzation, on the pivot pin 8 and are within the 7. Steelshells 10- a1e secured tou o enings A t Ie outer surface-of the rubberby bonding preferably during vulcniaation. Similar for the end of thejoint.

' A- pluralit the openings 5 and 7 into register the joint 'l elementmade'up of the pin 8 and the series of rubber members and shells can bescrewed into the opening and the joint thus Vas .,sembled. Set screws l`extendthrough each projectlon so as to lock the --shells 10 and 12against turning in` the projections after the element has beenl screwedto place. I prefer to havetheend shells at 'the ends of the.

joint protrude and, to screw -nuts 10* on .these protrudingl ends.-These'nuts maybe made to act as, lock washers and-when provided withcaps serve as a cover an`d finish When the 'weight is put on this jointthere is a slight movement endwise of the element due 'to the elasticityof the rubber. Thus the weightv on the projections 4 tends to move the,'shells 'l2 downwardly relativelyv to v ,the pin 8 and also to exertdown ward pres-` sure 'on the -pin8 whichis communicated to" the'members9 andthe members 9`yielding under' this pressure permit a :slight move-'ment of the pin 8 downwardly'relative to the projections 6. In order torevent a movement lwhich would bring -t e 'metal parts 'into contact andstill have all the parts reasonablyclose together it is desir-v able tovar the spacing between the units at the top of the shells 10 islgreater than at' the lbottom of these shells so that the downwardmovement ofthe. shells 12 under the'load will equalize the spacing.

I n Fi' 3 'and 4 I haveshown an im-v proved joint connection or hangerin conthisthere is a frame member 13 and spring connection 14. Onespring member has the p'lojectionsl and to the other spring memte'nlthrough the projections, these projectionsv having o enings larger thanthe pms.

'OP rubber members 18 are se# cured to` t e pins 17 lby surface bondingvand to a `series of shells., 19,'the shells being secured in theopenings' in the projectlons and 16,` A' connecting mem er' 20 has eyes21 and 23 atits ends which are formed with the' connecting member 20-nection with the multiple unit joint. In

i, the projections 116. Pivot pine 17 exby bending the connecting member20 in the form of a strap in opposite directions. The eye 2l has anextension .22 which extends along one side of the connecting strap 20and the eye 23 has an extension strap 22a which extends along theconnecting member 20. These parts are normally somewhat open and arebrought together and secured by clamping bolts 26, the closing of theeyes by bringing these eyes together clamping* these eyes on the shellsof the joint units arranged in the eyes. To adapt this device 'to' aplurality of units the strap member 20 is preferably notched or cut outat intervals so that the eyes are formed in projections which alternatewith the projections 15 and 16. It' preferred the eyes may be extendedin a loop-24 through which a clamping bolt c27 extends. The'wholeconnection, however,

is formed by bending a single piece of sheet metal.
